Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CE4 is the identified substitute for the obsolete MX6SWT-A1-0000-000CE4. Selection is based on the following factors:

Product Status: The substitute is classified as Active, ensuring continued availability and supply chain stability compared to the obsolete main part.

Compliance: The substitute carries RoHS Compliant certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Optical and Thermal Equivalence: Both parts deliver identical flux output (104 lm at 25°C) within the same range (100–107 lm), maintain identical CRI (75 Typ) and viewing angle (120°), and share identical thermal resistance (5°C/W) and physical footprint (5.00 mm × 5.00 mm).

Electrical Differences: The substitute operates at 3.3V forward voltage with 300 mA test current, compared to the main part's 20V and 60 mA. This represents a significant voltage reduction. Circuit redesign is required to accommodate this voltage difference. The substitute's maximum current rating (1 A) exceeds the main part (175 mA), providing greater current handling capability.

Efficiency Improvement: The substitute delivers 105 lm/W compared to the main part's 87 lm/W, representing an 18 lm/W efficiency gain at the respective test currents.

Package Consideration: The substitute features an exposed pad variant of the 2-SMD Gull Wing package, providing enhanced thermal performance through direct pad contact to the PCB.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CE4 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000CE4?

A: No. While both parts deliver identical optical output (104 lm, 4500K, 120° viewing angle, CRI 75), the substitute operates at 3.3V forward voltage compared to the main part's 20V. Direct substitution requires circuit redesign to accommodate the lower voltage requirement. The physical footprint and thermal characteristics are identical, but electrical circuit topology must be modified.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: color and CCT (White, Neutral 4500K), flux output range (100–107 lm at 25°C), CRI (75 Typ), viewing angle (120°), package configuration (2-SMD Gull Wing), physical dimensions (5.00 mm × 5.00 mm), thermal resistance (5°C/W), and moisture sensitivity level (2A). Variations in forward voltage, test current, and maximum current are allowable if the substitute meets the optical and thermal specifications.

Q: Does the exposed pad on the MX6AWT-A1-0000-000CE4 affect PCB layout?

A: The exposed pad variant provides enhanced thermal dissipation through direct contact to the PCB ground plane. PCB layout should include a thermal via pattern connected to the exposed pad to maximize heat transfer. The physical footprint remains 5.00 mm × 5.00 mm, but thermal design considerations differ from the standard Gull Wing package.

Q: What is the impact of the 18 lm/W efficiency difference?

A: The substitute delivers 105 lm/W at 300 mA test current versus 87 lm/W for the main part at 60 mA test current. This efficiency difference reflects operation at different current levels and does not indicate superior performance at equivalent operating conditions. Absolute flux output (104 lm) remains identical for both parts.

Q: Is RoHS compliance a factor in substitution?

A: The substitute is RoHS Compliant, while the main part does not specify RoHS status. If RoHS compliance is a design requirement, the substitute satisfies this requirement. Both parts maintain REACH Unaffected status.

Q: What inventory status should be considered?

A: The main part (MX6SWT-A1-0000-000CE4) is obsolete with 1,080 pieces in stock. The substitute (MX6AWT-A1-0000-000CE4) is Active with 970 pieces in stock, providing long-term supply chain assurance for new designs and production continuity.
